I The rotary intaglio printing machine is in dicated with a' housing, having the bodyportionwith the rounded bottom 20 which joins with theinclined front wall 21, and the rear vertical wall 22 that terminates in the supporting heel 23. Lugs 25, 26 and 27 are ig. 3 indicates a section of Fig. 2 onthe formed with saidbodypdrtion. Side walls 30 and 31 are detachably fastened to the body portion of the housing by means of the screws 32, which engage the threaded openings in the lugs 25, 26 and the supporting heel 23'. Legs 33 and 34 are respectively formed with side walls 30 and 31. Brackets 36, 37, 38 and 39 are formed with the side walls 30 and 31'. In the side wall 30 is formed the central journal bearing 40, with the end wall 400;, and in the side wall 31 is formedthereto. The holder 49 is recessed at 52 and has formed therewith the nose 53. The doctor blade 54' has formed therewith the bent erid55 with the outer bearing edge 56, which latter is shaped toexactly fit the surface of the shell 71 to'be' described, andthe other end of the. doctor blade is supported I .upon the top face of the nose '53. A clamp 57 "is indicated with the heel 58 and is fase tened to the holder 49, by means of the screws 59. The heel 58 bears on-the top face of the recess 52 and the other end of said clamp 57 bears on the blade 54, opposite the top face therefrom the} apron 51, at right angles Y of the nose 53 and thereby the said blade .54

is tightly secured in place. Journal lugs 62 extend from the holder 49 and are supported upon the shaft 44 by means of which the said holder 49 can swing on said shaft 44. -The bent end .55 can bearon the etched shell 71.

The lower 'en d of the apron 51 is threaded for the .ad]usting screW63, for which is'provided the'lock nut64. An elastic strip of I packing 65'is located upon the top face of the supporting heel 23--and enters the recess- 50 of' the blade holder 49, The function of the strip of packing '65 is toprovide a seal for the housing of the printingmachine, and prevents the entrancentair into and the exit of vapor from said housing. By means of the adjusting screw 63 the bearing edge of the bent end 55 of the doctor blade can be brought -to'bear with exactly the right pressure on the printing cylinder to be now which are to be printed. The said etching extends-into and below the outer cylindrical periphery of the shell 71 of the printing cylinder 70. A cup shaped head 74 with the journal end 75 having the end wall 75a is fastened to the shell 71 at one end thereof.

' The journal end 75 is rotatively supported in the bearing 40, and its end wall 75a is spaced from the wall 40a to form acavity 406. At the other end of the shell is fastened a similar cup shaped head 76 with the journal end 77 having the end wall 7 7 a, and the inner circular wall 7 8. In the bearing 41 of the side wall 31 is rotatively supported a bushing 79 with the threaded end 80 and the flange 81 having the cam faces 82 with the heels 83. The bushing 79 has formed therewith the journal bearing 84 with the end wall 84a and the outer bearing face 85. The journal end 77 is journaled in the bearing 84 and its end wall 7 7 a is spaced from the wall 84a to form a cavity 84?). The bearing face 85 functions with the .inner bearing face 43- of the side wall 31 as a thrust bearing for the bushing 79. 3n auxiliary handle 86 is in threaded nagement with. the threaded end 80 of the bushing 79, and its inner face 87 functions as a thrust bearing with the projection 42 The flange 81 extends into the cup of the head 76. Clutch balls 88 are located between the cam faces 81 andthe inner circular wall 78 of the head 76.

A U-shaped frame is designated in its entirety by-the numeral and comprises the side members 06, which have each' formed therein the bearings 97 and 98. A lower cross member 99 extends between the journal bearings 98," and has, formed therewith the threaded boss 100, which has in threaded engagement therewith the adjusting screw 101. A compression spring 102 has one end thereof located in the opening of the boss and its other end is supported in a cavity of the lug 27. An operating handle 103 extends from tbe'cross member 99. The journal bearings 98 are rockingly supported on the shaft 47 In the bearings 97 is fastened the shaft 104, which has journaled thereto the metallic sleeve 105. A wooden core 106 is mounted upon the sleeve and the latter in turn has fastened thereto a tubular shell 110 of v shell 110 constitutethe impression roller of hi the film is scraped from end fastened to the ,moember 112 and its other end is fastened to the member 113. The outer end of the member 112 lightly bears on the shell 71 and functions as a cans to preventair and foreign matter discharged from the strip that is being printed entering the housing of the machine and adulterate the inktherein. The member 112 also prevents the escape of vapors from said ink. The member 113 bears on the top edge of the inclined wall 21 and functions as a door to fill the housing of the printing machine with ink. The member 113 also prevents entrance into said housing of air and foreign matter and prevents the escape of vapors therefr0m.- A reel isindicated with stands like 117. The shaft 118 is supported in and fastened to said stands. A wooden core 119 is journaled on the shaft 118 and has Wound there- 0n the web 120 having the outer face 120a and the inner face 12% onwhich the machine prints. I

I To operate the printing machine, ink 125 is poured into housing by lifting the shutter member 113. Next the doctor blade 54 is adjusted by means of the adjusting screw 63, and locked in position by means of the lock nut 64. The outer end of the web 120 is guided over the shafts 44 and 45. ,The gauge collars 48 are now located in proper positlQIl on the shaft 45 to guide the web 120 in proper position with respect to the etching on the shell 71. The impression roller having the tubularshell 110 is swung 711p, by

bearing down on the operating handle 103,- to enable theweb 120 to be located between pulled from the printing machine it is cut, 7

moistened, gummed or otherwise manipulated as required. During the pulling of the web the friction between it the printing cylinder 70 and the impression roller,-causes the said cylinder 70 to rotate in the housing in the direction of the arrow A. By this means a film of'ink 125a is deposited on the surface of the -shell 71. The surplus ink the unetched surlot .face of the 'shell 71, by means of the bent end 55 of the doctor blade 54. The ink that remains deposited in the depressions on the shell 71 upon further rotation of said shell is printed upon the-face 120a of the web 120. When the cylinder 70,is rotated by the pulling of the web 120, the clutch balls 88 are automatically carried toward the heels 83, and thereby theauxiliary handle 86 and the bushing 78 do not turn. Therefore the outer bearing face 85 of the flange 81remains at rest and bears against the face 43 of the side wall 31 to prevent any leakage of ink from the housing at that point. The journal end 75 turns in the bearing and the jour-' nal end 77 turns in the bearing 84 of the bushing 79. Between the ends 75 and 77 and their respective bearings 40 and 84 are formed cavities in which ink gathers, which functions as a lubricant. When the ink in i the housing of the printing machine falls below the bottoms of said bearings, theink remainingin the cavities of the bearings 40 and 84 still provides a lubricating medium for the journal ends 75 and 77. The ends Of the shell 71 only bear against the inner faces of the side walls 30 and 31 at the upper portion of said walls, which prevent any lateral movement of the printing cylinder 70 and also practically seals said cylinder in the housing. The inner faces of the lower portions of the side-walls 30 and 31 arespaced fromthe ends of the-shell 71 as indicated in Fig. 6

It will be noted that the side edges of the doctor blade holder 49, the packing strip 65, the clamp 57," the doctor blade 54, the shell 71 and the shutterinembers 112 and 113 bear against the adjoining faces of the side walls 30 and 31 to form an air tight closure therewith. The distance between the contact line of the bearing edge 56 of the bent end of the doctor blade 54 and the line of tangency of the shell 71 and the impression roller is brought to a minimum, so that any exposed area of the cylinder with a filmof ink between these lines will be the smallest possible.

. This disposition is essential because the film reason of the coaction of the clutch balls 88 with the cam faces 82, and thereby no injury can result to the printing on the web 120.

The material of the doctor blade 54 is slightly softer than the material of the shell 71, so that any wear between these two ele-" ments will be of thedoctor blade in preference-to the shell. If the edge 56 of the blade 54 has been worn so as to produce a discoloring in the printing of the web 120, either a new doctor blade must be inserted or the edge dicated at 30 and 31. The U-shaped frame is again indicated with side members 96, which support the impression roller with the tubular shell 110. The printing cylinder-is again indicated with the annular shell 71. The packing strip on the heel 23 is again indicated at 65.

The doctor blade holder 130 bears on the strip and is shown. with the apron 131 similar to 51, and the adjusting screw 132 with the lock nut 133 are similar to 63 and 64. The doctor blade holder has in this instance formed therewith the depending flange 134 and the projecting lug 135, which latter has an upper face slightly above the openings in the lug 135. Each sleeve has an interior thread. A clamping bar 146 bears on the doctor blade and has four openings thatengagethe sleeves 144. Screws 148 are in threaded engagement with the threads of the sleeves 144 and their headsbear down on the clamping bar 146. Either of the contact ends 141 and 142 of the doctor blade 138 are formed to exactly fit the shell 71 as described for the bearing end 56 of the doctor blade 54, by reversing the blade 138.

The doctor blade may be made without bent end.
